Can't offer any explicit advice, but what kind of printer do you have???
I have several Brother printer models, and the brother homepage has
linux install scripts for all of them that work flawlessly with cups.
Just make sure /etc/rc.d/rc.cups has start'ed, turn on your printer
and make sure it's connected (presumably by wifi nowadays), and then
run the script. The necessary /etc/cups/, /usr/share/cups/, etc gets
automatically edited as needed, and the printers "just work" afterwards.
Not sure what similar linux install scripts other printer manufacturers
provide. But I'd suggest googling around for that first.
